These objects, which seem to extend from the earth to the heavens, are actually all ant mounds.
One of the world's largest structures was recently discovered in Brazil.
However, the producers are termites.
The ant mounds, which have been in the making for 4,000 years, have objects up to 3 meters high on the ground surface.
The amount of soil in those areas, which is almost the same as the entire land area of the United Kingdom, is 4,000 times larger than the pyramids at Giza, Egypt.
This ant mound group continues to expand.
While ancient structures are often protected, there are probably some historical objects that exist quietly in places that are beyond the reach of such protection.
